Description

  The present invention relates to a video display device and a video display method for receiving a digital broadcast provided from a broadcasting company or a distribution company through a spatial wave or a communication line and reproducing an arbitrary program (content).

  In recent years, digitalization of television broadcasting has been promoted.

  In Japan, digital broadcasting has been started by ISDB-T (Integrated Services Digital Broadcasting Terrestrial) standard developed from MPEG (Moving Picture Experts Group) 2 standard.

  The ISDB-T standard divides the frequency bandwidth per channel (channel) into 13 segments, and uses 4 to 12 segments of these segments to create a standard definition (SDTV) or high definition (HDTV) program (referred to as content). Can be provided). Note that HDTV programs use segments for three SDTV programs.

  For this reason, a simple video broadcast (sometimes referred to as partial reception) that provides a part of a program using only one remaining segment is defined, and the program has already been designated as a one-segment (one-segment) broadcast. Is provided.

  With the spread of digital broadcasting, recorder devices (video recording devices) that can record not only regular broadcast programs but also simple moving image broadcast programs and television receivers (TV devices) with a recording function have already been put into practical use. Has been.

  In addition, since a simple video broadcast program has a data size smaller than that of a normal broadcast, the recorded data is transferred to a video playback device (mobile terminal) configured to be portable (viewing). Method) is spreading.

Patent Document 1 discloses a moving image data transfer method for selectively transferring a simple moving image broadcast program among already recorded digital broadcast programs to a recording medium that can be played back by a mobile terminal.
JP2007-274562

  In the moving image data transfer method disclosed in Patent Document 1, when the data to be transferred is not data of a program of simple moving image broadcast, the data is re-encoded into data that can be played back on the mobile terminal. The video data having a different data size is transferred. Since re-encoding involves rate conversion, the time required for encoding depends on the original time of the program.

  An object of the present invention is to record a simple video broadcast program in a recorder device (video recording device) capable of recording a simple video broadcast program as well as a normal broadcast program or a television receiver (TV device) provided with a recording function. An object is to provide a video display device and a video display method capable of notifying the presence of video data and easily transferring video data recording a simple video broadcast program to a portable video playback device.

The present invention has been made on the basis of the above-described problems. In order to extract whether or not a simple video program is attached to a normal program, the normal program and the simple video program are recorded in a distinguishable manner. In the video / audio / program information extraction unit that adds the information of the video, the audio / program information extraction unit, and the video / audio / program information extraction unit, it is extracted that a simple video program is attached to the normal program. It is an object of the present invention to provide a video display device having a recording unit that records a simple moving picture program and a normal program independently.

  By using one embodiment of the present invention, a simple video broadcast program recorded in conjunction with (associated with) a normal program can be easily transferred to an external medium such as an SD card.

  In other words, when a simple video broadcast program is attached to a recorded normal program, a simple video broadcast program is displayed on an external device such as an SD card by executing “Quick Copy” displayed by the menu display. The medium can be easily copied or moved (a program whose copying is prohibited is permitted only to move).

  Therefore, user operability and convenience are improved.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a video display device with a recording function to which an embodiment of the present invention can be applied. The video display device with a recording function described below may be, for example, a television receiver in which a video display unit (monitor device) is integrally provided.

  The video display device 1 shown in FIG. 1 will be described later in accordance with a receiver 2 that receives a key code (control input) from a remote controller (hereinafter abbreviated as a remote controller) 11 and the key code received by the receiver 2. It includes a controller 4 that controls a tuner 4, a video / audio / program information extraction unit 5, a recording device 6, a recording control unit 7, a recording list control unit 8, and a reproduction signal processing unit 9.

  Although not shown, the controller 3 includes a main control IC (Integrated Circuit) or LSI (Large Scale Integrated circuit) that functions as a CPU (Central Processing Unit), a ROM (Read Only Memory) that holds a control program executed by the CPU, and the like. RAM (Random Access Memory) for providing a work area, non-volatile memory (Non Volatility Memory) for storing various setting information and control information, time management, and recording reservation set by user input, etc. Timer controller (Timer Controller) used for

  The tuner 4 is connected to an antenna (not shown), for example, as an input (data including video, audio, and program information) 12 and can receive a broadcast by a spatial wave (surface wave and satellite wave). The program (sometimes referred to as content) of the channel (ch) instructed via is received. In addition, as an input 12, for example, when a broadcast distributed from a cable TV station can be received by an optical cable (not shown), a program of a channel (ch) designated via the remote controller 11 is received. If the tuner 4 can be switched from data including certain video, audio, and program information to data including other video, audio, and program information, the tuner 4 need not be called a tuner. It may be replaced with a communication device that enables connection to a server on a network accessible via the network or a video supply site provided by a specific distribution company. Of course, it goes without saying that both the communication device and the tuner 4 may be prepared.

The video / audio / program information extraction unit 5 extracts video, audio, and program information from the signal output from the tuner 4. The video / audio / program information extraction unit 5 decodes the ch (channel) program acquired via the tuner 4 and outputs the video signal. In addition, an audio signal is obtained, and various data (program information), program attribute information (program genre, etc.) and the like that are supplied after being merged into the program are extracted. Note that the program information includes, for example, SI (Service Information) indicating that a simple moving image broadcast (referred to as one segment) program is attached. Therefore, as described later, by checking the management data portion attached in the MPEG (Moving Picture Experts Group) -TS (Transport Stream) system, which is a compressed video that is normally supplied in digital broadcasting, a program for simple video broadcasting Can be specified. Note that simple video (one-segment) broadcasting is sometimes referred to as partial reception, and partial reception is applied not only to video (video) but also to data (data broadcasting) and audio-only broadcasting.

  The recording device 6 is a rewritable large-capacity recording device (Hard Disk Drive, HDD) provided with a recording capacity of, for example, 250 to 1000 Gbytes. By changing the recording rate, a video signal of up to about 1000 hours is obtained. And audio signals can be recorded. Although the program held in the recording device 6 is not described in detail, the hard disk device of another video recording / playback device connected via a home network or server or the hard disk added to the video recording / playback device 1 Needless to say, it may be a device.

The recording control unit 7 writes a recorded program to the recording device 6, reads a program from the recording device 6, transfers program information to the recording list control unit 8, and a video (reproduced image) via the reproduction signal processing unit 9. Controls the output and the transfer of data to the data output unit 13, which will be described later. At the time of writing a recorded program to the recording device 6, the program decoded by the video / audio / program information extracting unit 5 The program encoded and read from the recording device 6 is decoded and output to the reproduction signal processing unit 9 at the subsequent stage. The recording control unit 7 is used to transfer a program held by the recording device 6 to a memory card or the like connected to the data output unit 13. When recording a program on the recording device 6, the recording control unit 7, when a simple broadcast (one-segment) broadcast program is attached to the normal broadcast program to be recorded, is shown in FIG. As described above, each is recorded independently in a separate file, and an identifier indicating that a normal broadcast program and a simple video broadcast program are linked is given.

Recording list control unit 8 is read from the recording device 6 to generate a recording list based on program information included in the decoded program in the recording control unit 7.

  The reproduction signal processing unit 9 generates an output video signal that can be displayed (reproduced) on the display 10 as a video (reproduced image), which is read from the recording device 6 and decoded by the recording control unit 7. Note that the reproduction signal processing unit 9 may be branched from the display 10 and output to an output terminal (not shown). That is, another display device (monitor device) independent from the display 10 or an analog recorder device or the like can be connected to the output end, and the output video signal is further processed on the device side connected to the output end. It is possible to do.

  The recording control unit 7 is further connected to a data output unit 13 which is a card reader / writer / memory slot or the like into which a semiconductor memory (card memory) or the like can be attached. The data output unit 13 may be an interface represented by a USB (Universal Serial Bus) port or the like, or may be a USB mass storage connected to the data output unit 13. The data output unit 13 may be a wireless communication device represented by, for example, Bluetooth (registered trademark).

  Next, an example of a method of transferring a simple video broadcast program among recorded programs to a memory card or the like set in an external medium, that is, a data output unit, using the video display apparatus outlined in FIG. Indicates.

  In FIG. 2, when a [recording list] key (not shown) of the remote control 11 is turned on (display of the recording list is instructed), a transfer mode in which a simple video broadcast program can be copied (transferred) to an external medium ( The operation menu is displayed (1).

  In (1), when a mode capable of copying (transferring) a simple video broadcast program to an external medium is activated, one of the normal broadcast programs recorded in the recording device 6 is acquired from the recording device 6. (2).

  Next, it is determined whether or not a simple video broadcast program is attached to the normal broadcast program acquired in (2) (3).

  When it is determined in (3) that a simple video broadcast program is attached ((3) -YES), in the recording list to be displayed later, a one-segment icon is displayed on the program. Is associated with the need to display " For example, the “one-segment icon flag” secured in a predetermined area (one-segment flag area or the like) in the main memory (RAM) is changed from “0” to “1” (4).

  Subsequently, it is checked whether there is another normal program recorded in the recording device 6 (5).

  By (2) to (5), it is checked whether or not a simple video broadcast program is attached to all programs recorded in the recording device 6, and when the check ends ((5) -YES ), An output video signal capable of displaying a recording list is generated based on the information (“one-segment icon flag”) obtained in (3). At this time, an output video signal capable of displaying a display screen as shown in FIG. 3 is obtained. Therefore, when the reproduction signal processing unit 9 and the display 10 are connected, a “normal recording list” screen as shown in FIG. 3 is displayed on the display 10. On the other hand, by connecting a monitor device to an output terminal (not shown), a “normal recording list” screen as shown in FIG. 3 is displayed (6).

  On the listed “normal recording list” screen, an arbitrary program in the list is selected by a [cursor] key (not shown) of the remote controller 11 (7), and a quick menu is displayed by a [quick menu] key (not shown) of the remote controller 11. Is displayed, as shown in FIG. 4, a “Quick Menu” display capable of copying the selected program to an external medium is displayed (8).

  In this state, when “Copy 1Seg to SD card” in the “Quick menu” display is selected by the user (9), the memory card (SD card) is set in the data output unit 13; If it can be checked that it is set, it is checked that there is enough free space, or that the recording capacity of the other party communicated via Bluetooth is sufficient and communication is possible (10), When the [OK] key (not shown) of the remote controller 11 is turned on, the program of the simple video broadcast selected in (7) is transferred to the memory card (SD card) set in the data output unit 13 (11 ).

  As described above, the simple video broadcast program attached to the normal broadcast program instructed by the user to be transferred to the external medium (SD card) is transferred to the SD card (not shown).

  The quick menu that can be selected by the user includes, for example, “apparatus information” display that activates a mode for displaying “apparatus information”, and “folder information” that activates a mode for creating a “folder”. “Create” display and the like are preset.

3 and FIG. 4, in the “normal recording list” screen 301 described with reference to FIG. 2 (6), as described with reference to (FIG. 2 (7)), the [cursor] key (not shown) of the remote controller 11 is used. If a program of simple video broadcast is attached to the highlighted program by selecting an arbitrary program from among the displayed programs in the list and, for example, highlighting (focusing), In the “recording list” screen 401 (FIG. 4), a “quick menu” display 411 is displayed as a pop-up, for example (FIG. 2 (8)).

Further, as shown in FIG. 5, in the "normal recording list" screen 501, the "program simplified video broadcast program comes with" indicates that the program of simplified video broadcasting comes with "icon (Individual Display marks, identifiers) ”521, 522,... May be displayed simultaneously with the display of the normal broadcast program.

In addition, as shown in FIG. 6, a “quick menu” (not shown) of the remote controller 11 is also displayed on a “full screen display” screen 601 in which a normal broadcast program or an arbitrary recorded program is displayed in a full screen display. By operating the key at an arbitrary timing, when a program of simple video broadcasting is attached , the “quick menu” display 611 can be controlled to be displayed as a pop-up, for example.

Note that, as shown in FIG. 7, for example, “recorded program search” is selected by a [menu] key (not shown) of the remote controller 11 and the “recorded program search result” screen 701 is displayed. for the program, "which is a program that comes, indicating that the program of simple video broadcast comes with" icon "721, 722,..., but" recorded program search result "individual program in the display screen 701 It is also possible to control the display so that they are displayed simultaneously. Further, when an arbitrary icon is selected via the remote controller 11, a “quick menu” display 711 is displayed as a pop-up, for example.

FIG. 8 shows an example of a setting method for setting whether to record an attached “simple video broadcast program” at the same time when an arbitrary program is recorded using the video display apparatus outlined in FIG. Indicates.

  In FIG. 8, when a “recording reservation” is selected by a [menu] key (not shown) of the remote controller 11, for example, a program table (program navigation (full screen list)) as shown in FIG. 9 is displayed. (101).

  When an arbitrary program to be recorded is selected by a [cursor] key (not shown) of the remote controller 11 in the displayed program guide (program navigation (full screen list)), a “reservation information setting” screen is displayed. . Here, it is assumed that “record a simple video broadcast program simultaneously” is selected (102).

  Hereinafter, when the reservation execution time of the program selected in (102) has been reached (103), the “reservation information” set in (102) is read out (104), and the program of the simple video broadcast is broadcasted normally. Whether or not to record simultaneously with the program is specified (105).

  In (105), when it is read (105-YES) that recording of a simple video broadcast program has been set at the same time, an identifier (“icon”) is assigned to the normal broadcast program and the simple video broadcast program. Information for display) is inserted. That is, when a normal broadcast program and a simple moving image one-segment broadcast program are recorded together with the normal broadcast program, an identifier is inserted so as to be understood as linked content (106).

  Subsequently, a normal broadcast program and a simple video broadcast program are recorded (107).

  On the other hand, in (105), when it is read that it is set not to simultaneously record a simple video broadcast program (105-NO), only a normal broadcast program is recorded (108). .

  As described above, in FIG. 8, a simple video broadcast program is attached to the program recorded (recorded) in the recording device 6 by (105-YES), (106), and (107). By associating that the broadcast program is also recorded with the data recorded for the normal broadcast program, as shown in FIG. 5 or FIG. 7, in the “recording list” screen or the “recorded program search result” screen, It is displayed that a simple video broadcast program is attached to the recorded normal program, and that the simple video broadcast program is also recorded.

  In (102), it is also possible to set the user setting so that only a simple video broadcast program is recorded.

  In addition, the degree of coincidence of the moving image between the simple moving image broadcast program and the normal broadcast program is large, for example, from "color information of image", "contour extracted from image", "frequency distribution of sound", etc. If it is determined that it is different from the simple video broadcast provided as a program partially extracted from the same content as the normal broadcast program, when the target simple video broadcast is recorded It is preferable not to link with a normal broadcast program by disconnecting the link (not interlocking). This is because if linked, it may be handled as if a simple video broadcast program actually exists. Specifically, for example, icons such as those shown in FIGS. 5 and 7 are displayed even though there is no simple video broadcast program, and the user is confused when there is a simple video broadcast program. According to this embodiment, such a problem can be avoided. That is, when the simple video broadcast is not a simulcast of a normal broadcast program, even if the simple video broadcast is recorded simultaneously with the normal broadcast program, the normal broadcast recording as shown in FIGS. It shall not be displayed at the same time as the list.

  Also, as shown in FIG. 10, a “normal recording list” display 1001 is displayed in a “quick menu” display 1011 displayed by pop-up or “quick menu” display. By preparing the “Play 1Seg” display 1031 that activates the playback mode (display of the operation menu) for playing the “simple video broadcast program”, the recording status of the simple video broadcast program can be confirmed and viewed. This is possible by a simple operation without using the simple video recording list.

  As described above, by using one of the embodiments of the present invention, a simple video broadcast program recorded in association with (associated with) a normal program can be recorded on an external medium such as an SD card, for example. Can be transferred easily.

  In other words, when a simple video broadcast program is attached to a recorded normal program, a simple video broadcast program is displayed on an external device such as an SD card by executing “Quick Copy” displayed by the menu display. The medium can be easily copied or moved (a program whose copying is prohibited is permitted only to move).

  Therefore, user operability and convenience are improved.

  It should be noted that the content of the present invention is not limited to the form described here, and it goes without saying that various other forms can be taken without departing from the spirit of the invention. In addition, the embodiments may be implemented by appropriately combining them as much as possible, or by deleting a part thereof, and in that case, various effects resulting from the combination or deletion can be obtained.
